A man purchased some fruits for Rs. 1000. He sold fruits worth 400 at 10% profit. At what profit per cent, must he sell the rest in order to gain 20% on the whole? | [
"33(1/3)%",
"None",
"26(2/3)%",
"30%"
] | C | Solution: To get 20 % profit on whole,
1000(CP)==20%(gain)==>1200(SP).
Total Profit = 1200 - 1000 = Rs. 200.
400 ==10%(gain)==>440.
He gets Rs. 40 profit on 400 hundred. Rest Profit = 200 - 40 = 160.
Then he must get Rs. 160 as profit on Rs. 600;
Hence, % profit = 160*100/600 = 26.66%.

16 men went to a restaurant. Fifteen of them paid Rs.80 each and the sixteenth man paid Rs.75 more than the average of all the 16 men. What is the total bill? | [
"1360",
"1460",
"1760",
"1660"
] | A | 15 paid Rs.80 each = 15*80 = 1200
total = x
then 16th man would have paid = x-1200
that is = 75+(x/16)
((x/16)=average)
equating these two
x-1200 = 75+(x/16)
x-(x/16)= 1275
15/16x = 1275
x = 1275*16/15
x = 1360

During a Thanksgiving weekend, a car rental company rented seven-tenths of their vehicles, including two-fifths of the 4WDs that it had. If 40% of the vehicles are 4WDs, then what percent of the vehicles that were not rented were not 4WDs? | [
"30%",
"20%",
"60%",
"40%"
] | B | 3/10 of all the vehicles were not rented.
(3/5)(2/5) = 6/25 of all the vehicles are 4WDs that were not rented.
(6/25) / (3/10) = 4/5 is the fraction of non-rented vehicles that were 4WDs
1 - 4/5 = 20% of non-rented vehicles were not 4WDs.

John went to a shop and bought things worth Rs. 25, out of which 30 Paise went on sales tax on taxable purchases. If the tax rate was 6%, then what was the cost of the tax free items? | [
"A)19.7",
"E)22.5",
"D)21.5",
"B)21"
] | A | Total cost of the items he purchased = Rs.25
Given that out of this Rs.25, 30 Paise is given as tax
=> Total ta x incurred = 30 Paise = Rs.30/100
Let the cost of the tax free items = x
Given that tax rate = 6%
∴ (25−30/100−x)6/100 = 30/100
⇒ 6(25 −0.3 −x) = 30
⇒ (25 − 0.3 − x) = 5
⇒ x = 25 − 0.3 − 5 = 19.7

Two persons start from two places 160 km apart at the same time with velocities 50 km/hr and 30 km/hr. move in opposite direction. Where they meet ? | [
"90 km from A",
"100 km from A",
"50 km from B",
"70 km from B"
] | B | Explanation :
Solution: d = 160, v1 = 50, v2 = 30
relative speed vr = v1 + v2 = 50 + 30 = 80.
the distance covered by them will be indirectly proportional to their distance
of the persons of meeting from A = 160*50/(50+30) km
= 160*5/8 = 100 km.
